Goulds GT20, IRRI-GATOR Self-Priming Centrifugal Pump, 86 GPM, 2 HP, 230 Volts, 1 Phase, 1-1/2" NPT Suction, 1-1/2" NPT Discharge

The Goulds GT Irri-Gator series of self-priming centrifugal pumps is built for dependability, efficiency, and easy maintenance.  In addition to lawn sprinkling, Irri-Gator pumps can be used for irrigation, air conditioning and heating systems, water transfer and dewatering applications. Discharges for this series are 1-1/2" NPT in size.

The Goulds GT series is constructed with solid cast iron frame. In addition, an “electro-coat” paint finish is applied to both the interior and exterior of the pump housing. Electro-coating simply uses electrical current to deposit the paint finish on the item, which is then baked in a curing oven. The process reinforces the casing for corrosion and abrasion resistance.

The impeller is a FDA-compliant, glass-filled Noryl impeller which is also corrosion resistant. Since the pump could be exposed to corrosive elements such as wind, rain, dirt and groundwater, corrosion-resistance is especially important. Thus, the Goulds GT series is perhaps the most reliable irrigation pump option for years of continued good service.

Self-Priming The Goulds GT series is built with a centrifugal self-priming design. Once the initial priming is performed, the pumps will reprime once the water level rises above the level of the suction pipe. The self-priming action makes it a convenient pump for lawn sprinkler systems designed to operate at certain pre-timed intervals. The pumps are also powered for continuous use off of the self-priming action. They can reach up to 25 ft. of suction lift after repriming.

Easy ServiceabilityA back pullout design allows for the ‘back end’ of the pump to be separated from the ‘wet end,’ which remains attached to the piping. Certain back end components, such as seals and bearings can thus be easily removed from the pump. This is of great convenience if a specific part needs to be cleaned, serviced or replaced but you don’t want to detach the wet end from your piping. The motor casing is also constructed with a two compartment design for easy access to the motor wiring. You can maintain parts of the pump when they need to be maintained without disrupting the whole of your system. Customers are more likely to take proper care of the pump and perform preventive maintenance because of the convenience of the back pullout design. And preventive maintenance is the best way to ensure consistent performance over the life of the pump.
